(54) Radio communication terminal device and radio transmission method


(57) It is possible to provide a radio communication terminal device and a radio transmission method which can improve reception performance of a CQI and a reference signal. A phase table storage unit (112) stores a phase table which correlates the amount of cyclic shift to complex coefficients {W1, W2} to be multiplied on the reference signal. A complex coefficient multiplication unit (113) reads out a complex coefficient corresponding to the amount of cyclic shift indicated by resource allocation information, from the phase table storage unit (112) and multiplies the read-out complex coefficient on the reference signal so as to change the phase relationship between the reference signals in a slot.
